This is a half-baked attempt to demonstrate resampling by hand.

A quick analysis of a comparison between sensitivity to frequency and orientation in Gabor patches. I am Ss 1 and 2. If you guys have any chance to run more Ss, that would be great. If you run Ss, they'll be run under the same version of the study as S2.

This is a quick analysis of data from a Steven's scaling experiment for the orientation of a Gabor patch. Currently the frequency is held constant, but the phase varies "randomly" from trial to trial.

Site supervisors' evaluation of interns.

This is the one from my laptop. It is more current than the other one from my home computer.

Interim results.

Analysis of survey data from social workers about their attitudes about four different kinds of beliefs as a function of years of experience and their race.

On 26 February 2015, Mike Pesca said that most bears cannot be smarter than the average bear, “that’s a tautology.” It is not. It is a property of the mean and symmetric distributions. If a distribution is asymmetric (also known as skewed), most of the data points in that distribution can be greater or less than the mean.

The simulation suggests that we can dramatically reduce the number of initial mis-classifications if the opt-in vs. opt-out decision is made based on class level. Some proportion of initial mis-classifications are going to become time-consuming issues for staff and faculty. We can likely reduce the number of time-consuming issues that staff and faculty have to deal with by taking class-level into account when deciding whether students should have to opt out or opt in.

Some potential errata in Kranzler's book, Statistics for the Terrified.

A description of why Bell's made-up-on-the-spot approximation to Bayes Rule worked for the in-class examples on Thursday.

In short — given the model, there's a 96% chance of getting more than 30 credits total enrolled in the class.

Examination of who is hated by males vs. who is hated by females — although I am not sure I am pulling out the right data…

A friend told me that NOAA's data indicated that global temperatures had been decreasing since 1998. He said that if I checked NOAA's website, I would see that he was correct. I too my best shot at confirming his claim and came up with this.

A quick demo of plotting moderation in R.
